The 2014 Outback is generally solid but the 2.5L H4 suffers from oil consumption issues leading to catastrophic engine failure if unchecked, while the CVT can develop cooler leaks and premature wear. The 3.6L H6 is far more reliable but rarer.
Excessive Oil Consumption / Piston Ring Failure (2.5L H4)
Common · high severityTypical onset: 60,000-120,000 mi
Symptoms: Blue smoke on startup or acceleration, Low oil warning between changes, Rough idle and misfires if oil gets critically low, Complete engine failure if run dry
Fix: Subaru extended warranty covered some through 2017, but now owner pays. Requires short block replacement or full engine rebuild with updated piston rings. 18-24 labor hours for short block swap at an indie shop.
Estimated cost: $4,500-7,000
CVT Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 70,000-130,000 mi
Symptoms: Red fluid pooling under engine bay, Burning smell from fluid hitting exhaust, Transmission overheating warnings on dash, Slipping or shuddering if fluid gets low
Fix: Steel cooler lines corrode where they pass through the subframe. Replace both lines and top off CVT fluid. 2-3 hours labor. Subaru updated the part design, so use latest revision.
Estimated cost: $400-700
Head Gasket Seepage (2.5L H4)
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: External coolant or oil weeping from cylinder heads, Slight coolant loss over time, No overheating initially, just slow seepage
Fix: The FB25 is better than the EJ25, but still sees external leaks eventually. Both head gaskets, timing components, water pump while you're in there. 12-16 hours labor. Not the catastrophic internal failure of older models, but still a significant job.
Estimated cost: $2,200-3,500
CVT Shudder and Premature Wear
Occasional · high severityTypical onset: 80,000-140,000 mi
Symptoms: Shuddering or vibration during light acceleration at 15-40 mph, Hesitation when merging or passing, Whining or grinding noises from transmission, Limp mode or won't move in extreme cases
Fix: Fluid changes every 30k can help but won't cure wear on the variator or valve body. Replacement CVT is the real fix. 8-10 hours labor plus core charge. Some early units had software updates that helped, but mechanical wear still happens.
Estimated cost: $4,000-6,500
Rear Wheel Bearing Failure
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Humming or grinding noise from rear that increases with speed, ABS or traction control lights if sensor damaged, Wheel play if severely worn
Fix: Hub assembly replacement per side. 1.5-2 hours labor per corner. Subaru hubs aren't particularly robust on this chassis, especially in salt states.
Estimated cost: $350-550 per side
Takata Airbag Inflator Recall (Front Passenger)
Common · high severitySymptoms: No symptoms until deployment, then risk of shrapnel injury, Recall notice by VIN from Subaru or NHTSA
Fix: Free recall repair at any Subaru dealer. Takes 1-2 hours, just verify it's been done before buying used. Check NHTSA database by VIN.
Estimated cost: $0 (recall)
Front Transmission Mount Failure
Occasional · low severityTypical onset: 80,000-120,000 mi
Symptoms: Clunk or thud when shifting from park to drive or reverse, Excessive engine movement visible when revving, Vibration at idle in drive
Fix: Pitch stop mount (front transmission mount) wears and separates. 1-1.5 hours to replace. Common enough on these that you should inspect it on any used purchase.
Estimated cost: $250-400
Buy the 3.6L H6 if you can find one; avoid high-mileage 2.5L CVT models unless oil consumption has been monitored and CVT serviced religiously—otherwise budget for an engine.
